Is there any way to detect Chinese characters using Perl? And is there any way on how to split Chinese characters with symbol dot '.' perfectly?

推荐答案

取决于您对汉字的特殊理解.也许您正在寻找/\p{Script=Hani}/，但是如果我们要扩大网络宽度，则以下正则表达式模式将匹配中文书写中出现的内容.如有必要，请限制.

Depends on your particular notion of what is a Chinese character. Perhaps you're looking for /\p{Script=Hani}/, but if we want to cast our net wide, the following regex pattern will match stuff that occurs in Chinese writing. Restrict if necessary.

use 5.014;
/
    (?: \p{Block=CJK_Compatibility}
    |   \p{Block=CJK_Compatibility_Forms}
    |   \p{Block=CJK_Compatibility_Ideographs}
    |   \p{Block=CJK_Compatibility_Ideographs_Supplement}
    |   \p{Block=CJK_Radicals_Supplement}
    |   \p{Block=CJK_Strokes}
    |   \p{Block=CJK_Symbols_And_Punctuation}
    |   \p{Block=CJK_Unified_Ideographs}
    |   \p{Block=CJK_Unified_Ideographs_Extension_A}
    |   \p{Block=CJK_Unified_Ideographs_Extension_B}
    |   \p{Block=CJK_Unified_Ideographs_Extension_C}
    )
/x;

是，.匹配一个字符. 拆分 DWYM的空模式:

Yes, . matches one character. The empty pattern for split DWYM:

use utf8;
split //, '冰淇淋'
# returns ('冰', '淇', '淋')
